21. Hydrodynamic Modelling for a Point Absorbing Wave Energy Converter
Sammanfattning : Surface gravity waves in the world’s oceans contain a renewable source of free power on the order of terawatts that has to this date not been commercially utilized. The division of Electricity at Uppsala University is developing a technology to harvest this energy. LÄS MER
22. Window Layer Structures for Chalcopyrite Thin-Film Solar Cells
Sammanfattning : This thesis aims to contribute to the development of improved window layer structures for chalcopyrite thin-film solar cells, with an emphasis on the buffer layer, to assist future reductions of the levelized cost of energy. This is realized by exploring the potential of existing materials and deposition processes, as well as developing new buffer layer processes based on atomic layer deposition (ALD). LÄS MER
23. Evaluation of biomedical microwave sensors : Microwave sensors as muscle quality discriminators in laboratory and pilot clinical trial settings
Sammanfattning : In this thesis the primary focus is on the evaluation of biomedical microwave sensor to be used in the muscle analyzer system. Lower muscle quality is one indicator that a patient can have sarcopenia. Therefore the muscle analyzer system can be a tool used in screening for sarcopenia. LÄS MER
24. An Integrated Approach towards Model-Based Mechatronic Design
Sammanfattning : Mechatronic design is an enigma. On the one hand, mechatronic products promise enhanced functionality, and better performance at reduced cost. On the other hand, optimizing mechatronic design concepts is a major challenge to overcome during the design process. LÄS MER
25. Stability of power systems with large amounts of distributed generation
Sammanfattning : This four-part dissertation is essentially concerned with some theoretical aspects of the stability studies of power systems with large penetration levels of distributed generation. In particular, in Parts I and II the main emphasis is placed upon the transient rotor angle and voltage stability. LÄS MER
